Abstract: In the title compound, diaquabis(1,10-phenanthroline-²N,N')zinc(II) fumarate tetrahydrate, [Zn(phen)₂(H₂O)₂]L·4H₂O, where phen is 1,10-phenanthroline (C₁₂H₈N₂) and L^2-  = fumarate (C₄H₂O₄), the zinc(II) cation is six-coordinated by two water molecules and four N atoms from two phen molecules. Each of the two independent L^2- anions is located about an inversion centre and does not coordinate to zinc(II) cations, acting rather as a counter-ion. The water molecules and L^2- anions are linked through a complicated hydrogen-bonding network to form a three-dimensional structure.
